Answer 1

Right-click your project in Solution Explorer and choose References.  Add Refence and select Microsoft.VisualBasic.

Make your main .cpp file look like this:

#include "stdafx.h"
#include "frmSplash.h"   // <--- Your splash form
#include "Form1.h"

using namespace cppSplashScreen;   // <-- Change this to your namespace
using namespace Microsoft:: VisualBasic:: ApplicationServices;

public ref class MyApp : WindowsFormsApplicationBase {
protected:
  virtual void OnCreateSplashScreen() override {
    this->SplashScreen = gcnew frmSplash;
  }
  virtual void OnCreateMainForm() override {
    // Do your initialization work here...
    //..
    System:: Threading:: Thread:: Sleep(5000);   // Pretend we're doing work

    // Then create the main form, the splash screen will automatically close
    this->MainForm = gcnew Form1;
  }
};

[STAThreadAttribute]
int main(array<System:tring ^> ^args)
{
  // Enabling Windows XP visual effects before any controls are created
  Application::EnableVisualStyles();
  Application:etCompatibleTextRenderingDefault(false);

  // Create app instance
  MyApp^ app = gcnew MyApp;
  app->Run(args);
  return 0;
}

Could just make a regular form with a timer, then when the timer reaches zero, close that form and show the main one?

Hi

i am having error at these lines

 

error C2059: syntax error : '>'

this->SplashScreen = gcnew frmSplash;

error C2664: 'Microsoft::VisualBasic::ApplicationServices::WindowsFormsApplicationBase::MainForm:et' : cannot convert parameter 1 from 'Form1 ^' to 'System::Windows::Forms::Form ^'

this->MainForm=gcnew Form1;

 

error C2872: 'Form1' : ambiguous symbol

could be '.\MyApp.cpp(10) : Form1'

or 'c:\documents and settings\cygoh\desktop\myapp\myapp\Form1.h(22) : MyApp::Form1'

Form1^ app=gcnew Form1;

 

i am using visual c++ express 2008 edition

thank you for your help

Answer 5

It looks like the class "Form1" is defined more than once and it doesn't know which you mean?

 

 

As for the other error, it looks like whatever function you're trying to use can't use "Form1" but needs a System.Windows.Forms.Form class.

Hi cygoh85,

From your post info above, the first error is caused by mismatched type.

this->MainForm=gcnew Form1;

The “MainForm”’s type is “Microsoft::VisualBasic::ApplicationServices::WindowsFormsApplicationBase::MainForm”, and “Form1”’s type is “System::Windows::Forms::Form”, you are unable to implicitly assign “Form” object to a variable  of “MainForm” type, it is illegal.

Form1^ app=gcnew Form1;

For ambiguous symbol issue, you can assign the scope like the following code snippet.

Form1^ app=gcnew MyApp::Form1;

For your information, there is an awesome sample about splash screen in .Net framework, though it is C#, I believe it is not a problem to convert it to managed C++ code.

By the way, you can upload your project to http://skydrive.live.com/

So that we can download it and do some troubleshooting.
